Abstract
Description
Technical Field
[0001] This utility model relates to the field of centrifuge liquid detection, specifically a centrifuge liquid concentration detection device. Background Technology
[0002] Centrifuges for solid-liquid separation of coal slime are key equipment that utilize centrifugal force to effectively separate solid particles from liquid in coal slime. Through the powerful centrifugal force field generated by high-speed rotation, the solid particles in the coal slime, due to their higher density, settle to the inner wall of the drum, while the liquid, due to its lower density, remains on the outer side of the particle layer. Finally, they are discharged through different outlets, achieving solid-liquid separation. This centrifuge has advantages such as high separation efficiency, large processing capacity, and small footprint. It is widely used in the field of coal washing and processing, significantly improving the recycling rate of coal slime, reducing water consumption, and playing a vital role in the clean and efficient utilization of coal and environmental protection.
[0003] Currently, determining whether a centrifuge sieve basket needs replacement during production primarily relies on manual sampling combined with visual inspection. Workers periodically extract samples from the centrifuge output and then visually observe the content and size distribution of solid particles to assess the basket's wear and separation efficiency, thus determining whether replacement is necessary. However, this method has drawbacks. Manual visual inspection is highly subjective, leading to inconsistent judgment standards among personnel. Furthermore, the limited precision of visual observation makes it difficult to accurately capture subtle changes, resulting in significant errors that impact production decisions. Utility Model Content
[0004] To achieve the above objectives, this utility model provides the following technical solution: a centrifuge liquid concentration detection device, comprising a detection structure, wherein the detection structure is installed at an external centrifuge outlet, the detection structure is a split design, comprising an outer structure, an inner structure fixed to the front end of the outer structure, and the inner structure having two sets symmetrically installed at the front end of the outer structure.
[0005] The outer structure includes a flange, and a display instrument is fixedly connected to the outside of the flange.
[0006] The internal structure includes a stainless steel tube, inside which is a quartz glass tube, and a photosensitive element is installed at the front end of the quartz glass tube.
[0007] The flange has two sets of openings on its inner side, and each set of openings is fixed with a set of nylon plugs.
[0008] Preferably, a rubber gasket is installed at the front end of the quartz glass tube, and a stainless steel wire plug is installed on the back of the front end of the rubber gasket.
[0009] Preferably, the rear end of the stainless steel tube is inserted into the corresponding nylon plug to fix the internal structure to the outer structure.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] This invention discloses a centrifuge liquid concentration detection device. This device uses optical principles to accurately monitor the concentration of particles in the liquid. Its built-in photosensitive element continuously and stably emits light signals to the receiving end. When there is no particle interference, the light signal can reach the receiving end smoothly. However, when particles are present in the liquid, the light signal cannot penetrate due to particle obstruction, and the intensity of the light signal received by the receiving end will change. Based on this, the device analyzes and obtains the concentration information of particles in the liquid, and quickly transmits it to an external display instrument. By checking the concentration data on the display instrument, the operator can accurately judge the wear condition of the centrifuge sieve basket and determine whether the sieve basket needs to be replaced.

[0017] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.
[0018] Please see Figures 1 to 3 This utility model provides a technical solution: a centrifuge liquid concentration detection device, including a detection structure 1, which is installed at the external centrifuge outlet and is a split design.
[0019] This detection device uses optical principles to accurately monitor the concentration of particles in a liquid. Its built-in photosensitive element continuously and stably emits light signals to the receiver. When there is no particle interference, the light signal can reach the receiver smoothly. However, when there are particles in the liquid, the light signal cannot be penetrated due to the characteristic that particles block the light signal, and the intensity of the light signal received by the receiver will change. Based on this, the device analyzes and obtains the concentration information of particles in the liquid, and quickly transmits it to the external display instrument 113. By checking the concentration data on the display instrument 113, the staff can accurately judge the wear condition of the centrifuge basket and determine whether the basket needs to be replaced.
[0020] The detection structure 1 includes an outer structure 11, and an inner structure 12 is fixed to the front end of the outer structure 11. The inner structure 12 has two sets and is symmetrically installed at the front end of the outer structure 11.
[0021] The outer structure 11 includes a flange 111, a display instrument 113 is fixedly connected to the outside of the flange 111, and two sets of openings are opened on the inside of the flange 111, with a set of nylon plugs 112 fixed in each set of openings.
[0022] The internal structure 12 includes a stainless steel tube 121, a quartz glass tube 122 is sleeved inside the stainless steel tube 121, a rubber gasket 124 is installed at the front end of the quartz glass tube 122, a stainless steel wire plug 125 is installed at the back of the front end of the rubber gasket 124, and a photosensitive element 123 is installed inside the front end of the quartz glass tube 122.
[0023] The rear end of the stainless steel tube 121 is inserted into the corresponding nylon plug 112 to fix the internal structure 12 to the outer structure 11.
[0024] When in use, the detection structure 1 is installed as a whole at the liquid discharge port of the centrifuge (see...). Figure 1 This centrifuge is mainly used for solid-liquid separation of coal slime. The screen basket is a vulnerable part because it is frequently rubbed and collided with solids. The liquid discharge port of this centrifuge mainly outputs a mixed liquid composed of small solids and water. When the screen basket is damaged and larger solids leak out, the detection structure 1 is equipped with two sets of photosensitive elements 123 (one photosensitive element is the light source transmitter and the other photosensitive element is the receiver). The transmitter continuously sends light signals to the receiver. The concentration of particles in the liquid is detected by using the principle that particles block the light signal and cannot penetrate. The concentration information is transmitted to an external display instrument. The staff can then determine whether the centrifuge screen basket needs to be replaced based on the concentration information.
[0025] The stainless steel tube 121 is mainly used for sealing and corrosion prevention, avoiding damage caused by long-term contact with liquid. Together with the stainless steel wire plug 125 and the rubber gasket 124, it can achieve end sealing of the stainless steel tube 121, prevent media leakage, and ensure overall stability. The quartz glass tube 122 has good light transmittance and will not block the photosensitive element 123. At the same time, the quartz glass tube 122 can play a secondary protection role. The two sets of photosensitive elements 123 transmit the measured data to the display instrument 113. By checking the concentration data on the display instrument 113, the staff can accurately judge the wear condition of the centrifuge sieve basket and thus determine whether the sieve basket needs to be replaced.
[0026] In existing centrifuges, the need to replace the sieve basket during production can only be determined manually by sampling the centrifuge output liquid and visually inspecting it. This method has a large margin of error. The detection structure 1 can effectively monitor the quality of the output liquid, improve production quality, and save labor costs.
[0027] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept.
